Chicago would become the largest U.S. city to ban plastic shopping bags from supermarkets if a group of aldermen get their way.
But that's the catch, because aldermen don't get their way in Chicago unless the mayor lets them. And it's not clear if Mayor Rahm Emanuel will allow the bag ban to come up for a vote when a City Council committee considers it next Tuesday.
The chief sponsor of the proposal, First Ward alderman Proco "Joe" Moreno, says the measure has wide support and should easily pass the health and environment committee. "I have not spoken to one alderman on the committee who's said no."
